Technical Field
[0001] The utility model relates to the technical field of automobile stamping dust covers, in particular to an automobile stamping dust cover with an inner wall sealing function. Background Art
[0002] Automobile dust covers are usually made by stamping using a mold. In order to ensure that the automobile shock absorbers maintain a good working condition, dust covers are usually used to prevent dust from entering, ensuring the normal use of the automobile shock absorbers. For example, in the patent with announcement number "CN214369908U" and the name of "A size-adjustable automobile headlight dust cover", a sealing ring is provided on the outer wall of the mounting base away from the telescopic cover body. The sealing ring abuts against the side of the limiting step away from the telescopic cover body. After the mounting base is connected to the headlight housing, the limiting step and the headlight housing jointly clamp the sealing ring to prevent dust and water vapor from entering the headlight housing and affecting the lighting effect of the automobile. However, the above structure still has the following problems during actual use:
[0003] When the above structure is in use, a set of mounting rings needs to be equipped under the device, and the sealing effect is achieved by fitting the mounting rings and the sealing rings. However, when it is used on a shock absorber and it is inconvenient to use the mounting rings, the sealing rings need to be set on the inner wall of the dust cover, and the sealing effect is achieved by fitting the sealing rings and the inner wall of the dust cover tightly. However, the dust cover needs to be put on from one side during installation, which makes it easy for the sealing ring to rub against the shock absorber during installation, and the friction makes the sealing ring loose, affecting the sealing effect.
[0004] Therefore, we propose that the automobile stamping dust cover with inner wall sealing function can well solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a stamped dust cover for an automobile with an inner wall sealing function, so as to solve the problem in the current market proposed in the above-mentioned background technology that the dust cover needs to be put on from one side during installation, which makes it easy for the sealing ring to rub against the shock absorber during installation, and the friction causes the sealing ring to loosen, thereby affecting the sealing effect.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stamped dust cover for an automobile with an inner wall sealing function, comprising a dust cover body and a sleeve for waterproofing that is sleeved on the outer side of the sleeve;
[0007] The invention also includes: a guide edge is fixed at the lower end of the sleeve, and the outer side of the guide edge is arranged in an inclined structure;
[0008] A fixing ring is provided at the lower end of the dust cover body, and a sealing mechanism is provided on the inner side of the fixing ring to achieve sealing through a sealing gasket.
[0009] Preferably, the sealing mechanism includes a connecting ring and a resisting ring, and both the connecting ring and the resisting ring are sleeved on the outside of the dust cover body, wherein the resisting ring is fixed on the lower end surface of the connecting ring.
[0010] Preferably, an external thread is provided on the outer side of the dust cover body, and the external thread forms a threaded connection with the connecting ring.
[0011] Preferably, the inner side of the interference ring is arranged in an inclined structure, and the lower end surface of the interference ring is in contact with the interference rod.
[0012] Preferably, the interference rod is elastically slidably connected to the fixing ring via a return spring, and both ends of the return spring are fixed to the fixing ring and the interference rod respectively.
[0013] Preferably, the lower end of the interference rod is fixed to the sealing gasket, and the sealing gasket is arranged in an arc-shaped structure, and there are four groups of sealing gaskets, wherein the four groups of sealing gaskets form a circular ring structure.
[0014] Preferably, the sleeve is elastically slidably connected to the dust cover body via a tension spring, and both ends of the tension spring are fixed to the dust cover body and the sleeve respectively, and three groups of tension springs are provided.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the automobile stamping dust cover with inner wall sealing function not only achieves the effect of sealing and dustproofing by the fit of four sets of sealing gaskets with the outer wall of the shock absorber, thereby avoiding the loosening of the sealing gaskets due to friction between the sealing gaskets and the shock absorber during the installation process, thereby ensuring its sealing and preventing the entry of water and dust, but also preventing rainwater from flowing along the dust cover body to the external thread or through the gap between the interference rod and the fixing ring, thereby improving the rainproof effect of the dust cover body, and at the same time achieving the effect of diversion, thereby diverting rainwater and further improving practicality. The specific contents are as follows:
[0016] The inclined structure on the inner side of the resistance ring is arranged so that the resistance rod is squeezed and slides inward. The sliding of the resistance rod drives the fixed sealing gasket to move inward synchronously, so that the sealing gasket contacts the outer wall of the shock absorber. The four groups of sealing gaskets fit together with the outer wall of the shock absorber to achieve a sealing and dustproof effect, thereby avoiding the friction between the sealing gasket and the shock absorber during the installation process, which may cause the sealing gasket to loosen and affect the sealing effect, thereby ensuring its sealing and preventing the ingress of water and dust.
[0017] Furthermore, through the threaded connection formed between the connecting ring and the external thread, the connecting ring moves downward and drives the fixed interference ring to move downward synchronously, so that when the connecting ring drives the interference ring further downward, the interference ring will apply pressure to the interference rod;
[0018] The setting of the sleeve can achieve a rainproof effect, which can prevent rainwater from falling directly on the dust cover body, and at the same time prevent rainwater from flowing along the dust cover body to the external thread or through the gap between the interference rod and the fixing ring, thereby improving the rainproof effect of the dust cover body;
[0019] Furthermore, a guide edge is provided at the lower end of the sleeve, and the outer side of the guide edge is provided with an inclined structure, which can achieve a diversion effect, thereby diverting rainwater and further improving practicality;
[0020] When the resistance ring rises to the point where it no longer contacts the resistance rod, the resistance rod can be reset by the elastic force of the reset spring, thereby causing the resistance rod to reset and the fixed sealing gasket to reset at the same time. At this time, the sealing gasket will no longer fit the outside of the shock absorber, and the dust cover body can then be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] See also Figures 1-6, the utility model provides the following technical solutions:
[0030] Embodiment 1: In order to solve the problem in the prior art that the dust cover needs to be put on from one side during installation, which makes it easy for the sealing ring to rub against the shock absorber during installation, causing the sealing ring to loosen due to friction, thereby affecting the sealing effect, the following solution is disclosed, comprising a dust cover body 1 and a sleeve 2 for waterproofing that is sleeved on the outside of the sleeve 2; further comprising: a fixing ring 8 is provided at the lower end of the dust cover body 1, and a sealing mechanism is provided on the inner side of the fixing ring 8, and a sealing effect is achieved by a sealing gasket 10, and the sealing mechanism includes The dust cover body 1 includes a connecting ring 5 and a resistance ring 6, and the connecting ring 5 and the resistance ring 6 are both sleeved on the outside of the dust cover body 1, wherein the resistance ring 6 is fixed to the lower end face of the connecting ring 5, and the outer side of the dust cover body 1 is provided with an external thread 7, and the external thread 7 and the connecting ring 5 form a threaded connection, the inner side of the resistance ring 6 is arranged with an inclined structure, and the lower end face of the resistance ring 6 is in contact with the resistance rod 9, and the resistance rod 9 is elastically slidably connected with the fixed ring 8 through a reset spring 11, and the two ends of the reset spring 11 are respectively fixed to the fixed ring 8 and the resistance rod 9.
[0031] When the dust cover body 1 is fully embedded, the dust cover body 1 is mounted on one end of the shock absorber. When it is fully embedded, the connecting ring 5 is rotated, and the threaded connection between the connecting ring 5 and the external thread 7 is formed, thereby making the connecting ring 5 move downward and driving the fixed interference ring 6 to move downward synchronously. When it moves to a certain position, the inner side of the interference ring 6 will contact the interference rod 9. At this time, when the connecting ring 5 is continued to be rotated, so that the connecting ring 5 drives the interference ring 6 to continue downward, the interference ring 6 will exert pressure on the interference rod 9. The inclined structure of the inner side of the interference ring 6 is set, thereby making the interference rod 9 squeezed and slide inward, and the sliding of the interference rod 9 drives the fixed sealing gasket 10 to move inward synchronously, thereby making the sealing gasket 10 contact the outer wall of the shock absorber. The four groups of sealing gaskets 10 are fitted with the outer wall of the shock absorber to achieve a sealing and dustproof effect, thereby avoiding the friction between the sealing gasket 10 and the shock absorber during the mounting process, causing the sealing gasket 10 to loosen and affect the sealing effect, thereby ensuring its sealing and preventing the entry of water and dust.
[0032] Example 2: A new technical solution is added on the basis of Example 1 to prevent rainwater from falling directly on the dust cover body 1, and to prevent rainwater from flowing along the dust cover body 1 to the external thread 7 or through the gap between the interference rod 9 and the fixing ring 8. For details, refer to Figure 1-Figure 3 A guide edge 3 is fixed to the lower end of the sleeve 2, and the outer side of the guide edge 3 is arranged in an inclined structure. The sleeve 2 is elastically slidingly connected with the dust cover body 1 through a tension spring 4, and the two ends of the tension spring 4 are respectively fixed to the dust cover body 1 and the sleeve 2, and three groups of tension springs 4 are provided.
[0033] At the same time, a sleeve 2 is provided on the outer side of the dust cover main body 1 as a whole, and the sleeve 2 is connected to the dust cover main body 1 through a tension spring 4. The setting of the sleeve 2 can achieve a rainproof effect, and can prevent rainwater from falling directly on the dust cover main body 1. At the same time, it prevents rainwater from flowing along the dust cover main body 1 to the external thread 7 or through the gap between the interference rod 9 and the fixing ring 8, thereby improving the rainproof effect of the dust cover main body 1. At the same time, a guide edge 3 is provided at the lower end of the sleeve 2, and the outer side of the guide edge 3 is arranged with an inclined structure, which can achieve a diversion effect, thereby diverting rainwater and further improving practicality.
[0034] Example 3: Add a new technical solution based on Example 1 to facilitate the removal of the sealing effect. For details, refer to Figure 3-Figure 6 The lower end of the resistance rod 9 is fixed to the sealing gasket 10, and the sealing gasket 10 is arranged in an arc-shaped structure, and there are four groups of sealing gaskets 10, wherein the four groups of sealing gaskets 10 constitute a circular ring structure.
[0035] When disassembly is required, just lift the sleeve 2 upwards, then reverse the connecting ring 5, and move the connecting ring 5 upwards through the external thread 7. At the same time, the connecting ring 5 drives the fixed interference ring 6 upwards. When the interference ring 6 rises to the point where it is no longer in contact with the interference rod 9, the elastic force of the reset spring 11 can drive the interference rod 9 to reset, and then the interference rod 9 is reset while driving the fixed sealing gasket 10 to reset together. At this time, the sealing gasket 10 will no longer fit the outside of the shock absorber, and the dust cover body 1 can then be removed.
